To all whom vit may concern.-

Be it known-that I, H. It'. H ILDEtrmof Lynnyin' the conntv- :"Essesg and' State of Massachusetts, have invern' afncw and useful Improvement in Machine nl" ",.rc that the tbllowing is a full, clean', and cx'ict de'- scription thereof', which will enable those skilled in the reference being had to the accompanying drawings, forming part of this speciiicatiou.' l

This invention lrelates to a in'achine ihruntwisting and picking hair-rope, thereby rendering it. suitable for use in upliolstciing, or other purposes; and

It consists in a. machine, constructed as hereinafter described, lbruntwisting theropeand pickingthc huir at one and .the saine time, thereby string much valuable uuic uid greatly reducing the cost ofthe article.

Figure 4 isatlfansverse section of lig. 1, looking from. the line -z z, in vthe direction of the upper .'irrow'. rFigure 5 is' a detailed view of the gearing on the ends ofthc'feed-rolls, showing the coupling,r on. the end of the lower feed-roll shait, for stopping the niotion of the rollers.

Similar letters of reference indicate corresponding parts. y

It is probahlywcll known thutthe curled hair used in upholstery is composed, for the most part, of long hair, (inanes and tails of horses and ent-tie) which is' subjected to a heating-process .and twisted into rope,

To rende-1' it available for the purposes to which it isapplied, (upholstcring,) the hair-rope must be um 'twisted and'picked so that itwill lie loose like wol.

In carrying out my invention, l construct :i` nniclinr of suitable. dimensions and of suitable materials for drawing tlie'hairLropc lfrom a loose drum, on which it I I is wound, anduntwisting it hy the revolution ol' the shaft on which thc drum is placed, then feeding .it between rolle-is to a picking-cylinder, which sepa-rates' the hairs and renders it fit for use.

A represents the tia1nc,'which may be inode of citheiwood or metal. -i

B is the unwindingshaft.

C is 'a ily-wheel on that shaft.

This shoi't is actuated bythe bevel-gears D E, to

which motion is imparted bv'the belt or vbond F from the pulley Gon thc pickerfcylimlcr shol't', by means of the pulley H and gear-wheel shaft- I.

'Y o is :i i"lisk-plo[e on the shaft B, throughs-high the rope passes heihrc it enters the shaft.

0n the end oi' the shaft B, there is a ciccp, P, -t'ornn-id of" two or more sections, which are hngedio a collar on the shaft.

sections-:tre made to clasp the rope-with 'a lorcc suliicient for untwisting it, aait is drawn into the machine by 'the leed-rollers.

R represents the uppericed-roller, and S, the lowcr iced-roller.

These rollers are groored or serrated -so that they may more Ireadily hohl and draw the' rope from the li-uni, und in contact with the picking-cylinder.

The leed-rolls are actuated from the shaft l the spring y.

the lower feed-roller S. Y Motion is imported to the upper feed-roll lh y menus oi' geur-wheels :c y on the -ends of those rolls' outside the foune, as seen in the drawing.

s is a. coupling or clutch on the end oi' the shzn't uf.

This coupling has two pins, ac, which enter holes, c c, in the gear y, thus coupling them together when they are in operation. -Wherr,l from any cause, it becomes necessary to stop the feed, the shnitwis given n. loogitin'linol motion h r the shipping-har d and laver e, which are operated by the attendant la). means of the hand-lever f, geen 'm lig.V 4.
